The 20 LARGEST Engines Ever Put in Old Cars!

Video Description

Ever wondered what automotive engineers were thinking when they decided a 6-liter engine just wasn't big enough? In this video, we explore the most outrageously oversized engines ever fitted into classic cars - mechanical monsters that make modern V8s look like toy motors. From Bentley's massive 8-liter straight-six to Bugatti's aircraft-derived 12.7-liter Royale engine, these pre-war powerplants represent an era when fuel economy didn't exist and bigger was always better. We'll journey through automotive history's most excessive creations, including secret prototypes with 13-liter straight-twelves, supercharged Auburn speedsters, and the legendary Cadillac V16 that started it all. These aren't just engines - they're monuments to an age of unlimited ambition and zero restraint. #classiccars #vintageengines #automotive #carhistory #engineering --------------- 00:00 intro 01:05 Bentley 8 Litre Straight-6 02:53 Pierce Silver Arrow V12 – 462 cu in 04:40 Alfa Romeo Tipo 162 – 4.2L V16 06:34 Tatra V12, 447 cu in 08:29 LaSalle V16 Prototype, 500+ cu in 10:25 Packard Straight-12 Prototype, 790 cu in 12:17 Chrysler Imperial Airflow 384 cu in Straight-8 14:12 Auburn 851 / 852 Supercharged Straight-8, 280 cu in 16:06 Stutz DV-32 Straight-8, 322 cu in 18:06 Rolls-Royce Phantom III V12, 447 cu in 20:01 Mercedes-Benz 770K, 7.7L Straight-8 21:53 Isotta Fraschini Tipo 8A, 7.3L 23:48 Duesenberg Model J, 420 cu in 25:41 Bugatti Royale, 12.7L Straight-8 27:29 Hispano-Suiza J12, V12, 754 cu in 28:12 Lincoln Model K, V12, 448 cu in 31:07 Packard Twelve, 473 cu in 32:58 Pierce-Arrow V12, 462 cu in 34:40 Marmon Sixteen, 491 cu in 36:22 Cadillac V16, 452 cu in ---------------
